TCL Communication claimed that their Go Flip 4 battery can last up to 18 days standby or 12 hours talk time. We believe that the phone battery lasts that long because we might only use it for basic activities and nothing heavy. Is the Alcatel Go Flip 4 a good phone? I really wanted to like the Go Flip because KaiOS has so much potential. An easily extensible, HTML5-based feature phone OS could bridge some of the gaps between smart and feature phones, keeping up with new talk and messaging services as they arise. It's a great idea. The Go Flip is available on Sprint and T-Mobile . For both carriers, it's part of a push to shift customers from 2G, which most voice phones still use, to 4G LTE, so the carriers can retire the old 2G networks in the future. (For what it's worth, both Sprint and T-Mobile intend to keep 2G alive for at least two more years.) As of this writing, it's the only low-cost feature phone those carriers sell. Design and Call Quality

Call quality is good. The phone supports HD calling (but not EVS, the second level of HD) and the earpiece is loud and clear. In a loud environment, the phone worked hard to cancel out noise, resulting in a few audio artifacts but generally comprehensible speech. The speakerphone is loud, and shows a little bit of clipping and distortion at top volume. Wi-Fi calling is the one real quality fail, but it often is; on a weak or cluttered 2.4GHz Wi-Fi signal, you're going to get dropouts. The Go Flip's camera is simply bad. There's a 2-megapixel main camera, which records 320-by-258 video. Images look yellow or bluish, blurry or like the lens is coated in Vaseline. The video mode only gets up to a jerky 20 frames per second in good indoor light, and the screen image kept tearing when I recorded. Alcatel also told me this phone will have—get this—50 percent better standby battery life than the previous model, which had 12 days of quoted standby time, but which many buyers said had more like three days after the fact. That's without increasing the device size. The 1,350mAh battery is still removable, too. But when we attached a Plantronics Voyager Focus UC headset, the Go Flip's old Bluetooth 3.0 connection struggled. Calls in the headset sounded thready, and my voice was highly compressed, at one point so squashed that an IVR had trouble telling what I was saying.Otherwise, the specs here are as basic as the previous Go Flip: a Snapdragon 210 processor, 512MB of RAM, 4GB of storage plus a MicroSD card slot, a 2.8-inch, 320-by-240 main screen, and a 2MP camera that is sure to not be very good. On T-Mobile and Metro, but not AT&T, it will have a hotspot mode, but the hotspot probably won't be very fast. A battery that can be removed is definitely an advantage. Should there be any damage to the battery, we can always find a replacement instead of throwing the phone away. Google Assistant is good for more than just messages; hold down the button and ask it a question, and it will respond with Google answers. I wish it could be triggered from the action button on a Bluetooth headset, though —you actually have to hold down the center button on the phone's D-pad to make it work.

Alcatel GO FLIP™ 4 - Easy as you think, smarter than you

We also thought that the phone didn’t have enough tools to make our lives easier. It isn’t smart enough, especially for the next generation of expressive users who constantly want more than just being connected to people.KaiOS, which is based on the same core that previously gave us Firefox OS, sits on the fence between a feature phone and a smartphone operating system. It's really rendering a lot of HTML, and the apps are primarily HTML5 containers that run offline. The OS has become popular in India thanks to the low-cost Jio Phone, a device that has brought tens of millions of people online for the first time. The KaiOS interface may be all HTML5, but it looks just like other old-school feature phones: a grid of big icons with commands attached to Left and Right buttons below the screen. The colors are bold, the fonts are attractive, and the icons are clear, but once again it's all quite sluggish. It's all of the overhead of HTML5 with none of the apparent flexibility or extensibility, at least on this phone. The onboard music player, oddly, wouldn't play music I had stored on an SD card—I had to transfer it into internal memory. Once I did that, though, it had excellent support for metadata and album art. The video player can play videos from the SD card, but they look small and grainy on the low-res screen. There's also an FM radio, which sounds very clear.

There's been a crisis in flip phones over the past few years. US carriers are reducing their 2G and 3G networks and focusing on 4G calling, which many older and less expensive phones don't support. Simple phones that support 4G calling have been hard to find. The Go Flip runs on a Qualcomm Snapdragon 210 processor, like other modern feature phones. The T-Mobile version has LTE bands 2/4/12, and the Sprint version has 25/26/41. I didn't have any RF problems indoors or out, and T-Mobile users will see a significant coverage advantage with this phone over one that relies primarily on 1900MHz 2G. Both models support Wi-Fi calling, on 2.4GHz networks only, and both have GSM/UMTS for international roaming. (According to Sprint, its model only roams within North America because of Sprint business policies.) The less said about the phone's single 2-megapixel camera, the better. Photos in even decent indoor light tend to be blurry and indistinct. Outdoors, everything looks slightly out of focus. Videos are washed-out 352-by-288 frames. There is also no front facing camera, so don't expect to do video calling here. The speakerphone isn't great. The speaker itself is bottom-ported, so it faces away from you, and it isn't very loud. More importantly, speakerphone microphone transmissions on the Sprint network came through as disappointingly muddy.It's funny: The older Go Flip 2 also has a Snapdragon 210, but it doesn't perform nearly as well as the new model does. Alcatel said that KaiOS 2.5 is much more efficient than the KaiOS 1.0 on the older phone, and it really shows.
